Patented Au 12,1913.

Application filed September 28, 1911. Serial No. 651,707.

To all whom it may concern:

Be it known that I, ALFRED A. ANDERSON, a citizen of the United States,and resident of Jamestown, in the county of Chautauqua and State of NewYork, have invented new and useful Improvements in Joint-Fastenings forFurniture, of which the following, taken in connection with theaccompanying drawings, is a specification.

The invention relates to improvements in fastening devices forfurniture; and the object of my improvement is to provide a simple,strong and convenient device for removably fastening together two partsof a piece of furniture, and the invention consists in the constructionand arrangement of the parts as described in this specification andshown in the drawings, and pointed out in the claims.

In the drawings, Figure 1 is a rear elevation of a dresser showing myjoint fastening as used for attaching the mirror supporting frame to thebody of the dresser; and Fig. 2 is an enlarged detail elevation of oneof the fastenings as attached to the rear of the dresser and mirrorsupporting frame. Fig. 3 is a side elevation of the attached fasteningfrom line X X in Fig. 2; and Fig. 4 is a similar view with the parts inthe unconnected position and without the wedge. Fig. 5 is an elevationof the wedge showing the preferred contour of the same. Fig. 6 is anelevation of the upper end of the fastening as attached to the dresserand mirror frame, the mirror frame being shown in section at line Y Y inFig. 1.

Like numerals of reference refer to corresponding parts in the severalviews.

The numeral 10 designates the body of the dresser, and the numeral 11the mirror frame. It is obvious that these two parts must be firmlyunited, yet so that the mirror frame may be quickly and easily removedfrom the body of the dresser.

The joint fastening consists of two plates 12 and 13 which are connectedat 14 at each side of the central raised loop portions 15; the raisedportions 15 having opening 16 between the two connect-ions 14 in orderthat said raised portions may not bind upon one another in connectingthe parts. The con.- nections 14: at each side of the raised loops 15consist of the outward and upward turned flanges 17 on part 12 and thehooked flanges 18 on part 13, which flanges 18 are made to hook over theupwardly turned flanges 17 thereby forming a complete connection betweenthe two parts 12 and 13 which does not permit of their separation whenthe tubular wedge 19 is inserted in the two raised portions 15. Theraised loops 15 are preferably made in the V-shape angular form andgradually diminish to ward the lower end on part 13, said lower end ofthe raised portion being left open. The wedge 19 is preferably made ofsheet metal and curved outwardly lengthwise on its inner and outer sidesand is made to fit within the raised loops 15 so that by means of saidcurved sides the wedge will hold strongest at the joint 20 between thetwo parts 12 and 13 and adjacent the opening 16.

10 attach this simple joint fastening to the pieces of furniture, part12 is attached to part 11 by screws adjacent to the joint 20 between thetwo parts 10 and 11. The part 13 has slots 21 for the upper screws. Saidpart 13 is then attached to the part 10 and adjusted as desired so thathooked flanges 18 will hold firmly over the flanges 17 at each side,thereby forming a strong connection 1 1, after which the lower screw 22is inserted, thereby securing all the parts in the adjusted position.The wedge 19 is then inserted and driven to place with a light tap ofthe hammer. A space 23 is provided in the lower end of part 13 for thelower end of wedge 19. It is apparent that the wedge 19 may be quicklyand easily removed from the raised loops 15 by a blow of the hammer onthe lower end of the wedge.

The wedge 19 is preferably made with inturned edges 24 which bearagainst both parts of the piece of furniture. The curved inner side ofthe wedge 19 causes the upper and lower ends 25 to bear against the twoparts 10 and 11 of the piece of furniture, thereby pressing the frame 11forward upon the top of the dresser 10 and insuring a tight joint 20between the two parts, and the curved outer side of the wedge insuresthe tight holding of this joint.

I claim as new:

1. In a device of the type set forth, a pair of plates arranged inconfronting end to end relation, means to detachably connectsaid platesto one another at their said confronting ends to prevent lifting of theupper part of the two parts to be connected from the lower part, a loopcarried by each plate and arranged in alinement with each other, and aWedge for engagement in said loops.

2. In a device of the type set forth, a pair of plates arranged inconfronting end to end relation, means to detachably connect said platesto one another at their said confronting ends, a loop carried by eachplate and arranged in alinement with each other, and a tubular wedge forengagement in said loops, the longitudinal side portions of the wedgebeing turned inwardly to provide substantially Wide and flat bearingfaces which extend in the same plane as, and are for engagement with therear faces of the parts to be connected.

3. In a device of the class described, a metal plate, a raised taperedloop on said metal plate to provide a tapered opening therethrough, asecond metal plate, a raised tapered loop on said sec-0nd metal plate toprovide a continuation of the tapered opening of said first loop, asheet metal tapered wedge formed to fit within said loops to holdagainst the furniture parts and said loops each side of the joint, saidtapered Wedge curved outwardly in its central portion and the inneredges turned toward one another to bear against said furniture parts andsaid loops each side of the joint to rigidly hold the same.

a. In a device of the type set forth, a pair of plates arranged inconfronting end to end relation, a loop on each plate, the loops of thetwo plates being alined, and a tubular wedge for engagement in saidloops, the longitudinal side portions of the wedge being turned inwardlyto provide substantially wide and flat bearing faces that extend in thesame plane as, and are for engagement with the rear faces of the partsto be connected.

5. In a device of the class-described, a plate having a tapered V-shapedraised portion to form a socket and means for attaching said plate,outwardly turned flanges on the lower edge of said plate each side ofsaid raised portion, a second plate having a tapered central V-shapedraised portion in line with the raised portion 'of the first of saidplates, a tapered wedge to insert Within said raised portions, andhooked flanges each side of said raised portions onthe upper edge ofsaid second plate to detachably engage over the outwardly turned flangeson said first plate.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
